2 Claims.

The invention herein disclosed relates to a wall construction of thetype made up of a plurality of wall boards,

Heretofore, various attempts have been made to provide awallconstruction with the use of commercially available wall boards whichwould be as satisfactory as a lath and plaster wall.

Such attempts have not, however,- met with successbecause of variousfactors, and particularly lbecause of the fact that the vertical columnsor supports to which the wall board is secured are frequently twisted.When the adjacent edge of two successive wall boards meet at a twistedsupport, a sharp edge or bulge is formed in the surface of the wall.

By the invention herein disclosed, there is provided a laminated wallconstruction utilizing wall board which is as smooth and as satisfactoryas a lath and plaster wall. In accordance with the invention, wailboards are secured to the vertical supports to form a wall base. Thesewall boards are so positioned that the adjacent edges of successive wallboards meet at a vertical support. Additional wall boards are fastenedto these base wall boards and form the outer surface of the wall. Theselatter wall boards are preferably glued to the base wall boards and areso arranged that they overlap the joints between two successive basewall boards and provide a smooth continuous wall surface.

A wall constructed'in this manner is illustrated in the accompanyingdrawing in which the single figure represents a horizontal sectionthrough a wall. In the drawing the element's i, 2 and 3 represent theusual vertical wall supports or two by 4 thesesupports that the wallboard which forms the wall surface is secured.

The condition which occurs when one ply of wall board is utilized inconstructing walls is i1- lustrated at the support 2 by the base wallboards 4 and 5 which are secured directly to the supports. The adjacentedges of two successive wall boards must meet at a vertical support inorder to be properly supported and the ends of the wall boards arecommonly nailed to the support. When the edges of two successive boardsmeet at a twisted support, there is a sharp break in the surface of thewall as indicated by the outer surfaces of the base wall boards 4 and 5at the supportl. This condition has prevented the general acceptance ofwall board in the construction of walls.

By this .invention sharp breaks in the outer surface of the wall areentirely avoided and a stronger'wall is secured. As indicated in the 5drawing, a laminated wall board construction is provided. The base wallboards 4 and 5 are secured to the vertical supports in the usual way, bynails 6. This base wall board is preferably a gypsum wall boardone-quarter of an inch 10 thick, but any outer wall boards such as fiberwall boards are suitable. The outer surface of these base wall boardsare then covered with an adhesive such as Casco glue.

} Against the outer surface of these base wall 16 boards, there issecured outer wall boards I and 8 which may also be secured, by nailing,to the supports at least until the adhesive between the boards dries.These outer wall boards are so arranged and positioned that the edges ofsuc- 20 cessive wall boards meet as a vertical support other than asupport at which the edges of successive base wall boards meet. Asillustrated the adjacent edges of the base wall boards 6 and 5 meet atthe support 2 and the outer wall 25 boards I and 8 meet at the support3. The outer wall boards thus overlap the joints of the base wall boardsand where thebase wall boards meet at a twisted support, the outer wallboard covers the abrupt break in the base wall board 30 and forms agraceful curve of large radius that is imperceptible to the eye. Whenthe outer wall boards meet at a twisted support, the base wall board, asshown at the support 3, forms a flat smooth surface spanning the twistedsupport 5 and there is no abrupt break in the outer surface of the wall.

The space between the edges of successive wall boards of the outerlayer, or joint as it is usually called, is filled in the usual mannerand the wall may then be finished.

It will be apparent to those skilled in the art that by this wallconstruction there is provided awall that is satisfactory in allrespects; that is less expensive than the ordinary lath and plasterwall; and that may be finished soon after it is erected.

It is obvious that various changes may be made by those skilled in theart in the details of the embodiment of the invention illustrated in thedrawing and'described above within the principal and scope of theinvention as expressed in the appended claims.

I claim:

1. A. laminated wall construction comprising a series of spaced,vertical supports, a series 01' wall boards secured to said supports andforming a continuous wall base, the adjacent edges of successive wallboards meeting at a vertical support, and additional wall boards securedto said base wall boards and forming a continuous wall surface, theadjacent edges of such successive wall boards meeting at a support otherthan a support at which the adjacent edges of 4 10 successive base wallboards meet.

2. A laminated wall construction comprising amasw
